Peach's Birthday Cake is Peach's board in Mario Party. Players needed to collect stars to complete the cake. Its main feature was the Flower Lottery, where a player plants a Red, Blue, Yellow, or Green seed (at the cost) and grows a flower which will either have a Toad or a Bowser face on it. This is run by a Goomba, who says if a player get the Bowser face, he will win the lottery and go to Bowser, who will sell him the Bowser Cake, one of Bowser's Phoney Items. If one get a Toad face one will lose the lottery and go in the direction of the Star. If a player landed on a ? space, they would have the opportunity to plant a "Strawberry Seed" at the cost of 30 coins, which grows into a Piranha Plant. Once planted, if another player with stars lands on the ? Space with the Piranha Plant there, it will steal a star from that player, and give it to the player that planted it. The player who planted a Piranha Plant will not be attacked by it when he/she lands on that space.
At the end of the game, the winner's stars formed into a large star that flashes and the board turns into a beautiful birthday cake. The winner, along with the players in 2nd and 3rd place, Toad, Koopa, Boo, Goomba, a pair of Piranha Plants, and the Star accompanying celebrates the victory, while the player in 4th place gets bit in the butt by another Piranha Plant.
